Availability of Alternator Connector?

I’d like to replace the 3-wire connector which mates with the back of my alternator.

Is this connector available with flying leads that I can splice/solder into the wires of my existing harness? Obviously I’d rather not buy a partial harness just to obtain this connector. Hopefully someone here may be familiar with the correct vendor and can point me in the right direction.

My intention is to also splice in monitoring wires for the ignition signal and battery sense terminals, so that I can observe these voltages while driving. I’ve replaced both my battery and alternator, and I’m still getting erratic charging. Sometimes the charging is normal (13.8 V), but then at other times there seems to be no charging at all and the ignition/lights/accessories gradually drain the battery.

When this happens, my alternator also seems to quickly become hot to the touch. The alternator I just removed did this also. Swapping the battery with a known good one from my other truck did not alter the results.

 

Just what is damaged the plastic part of the plug ?? The pins?

90980-11349 is the connector #

I need to hunt for the pin Part # I know you can buy the crimped pins.

 

I can take that number to a parts house and purchase a complete connector with leads?

 

That is the Toyota part #

Here is the female pin pig tail Toyota part Number 82998-12200 you need 3

Order from your dealer.

Just where have you searched ?

I would think a search should turn up many options

 

Toyota offers the bare connector. You then buy wire with pins pre crimped. There are standard and gold plated options in 150mm and 300mm lengths. I'd just stick with the standard pins and solder it together. The short regular pins are $15 each and the connector should be around $20.

 

Thanks!

I showed the picture to all the local parts stores (OReilly, Auto Zone, Advance, etc). All just shook their heads and said it was a dealer-only item.

I was hoping someone here might know differently.

 

OK, that’s interesting. If the connector doesn’t come preassembled, I guess I’d keep my undamaged shell and just buy the pins.

My next question would be whether I’d have to buy a special tool to extract the old pins from the shell.

 

If you search using your search engine of choice ( Tacoma 99 Alternator plug) I had several options come up with a assembled connectors .

I have always my own small tools by modifying something to work.

 

A small depinning tool works well. They're super cheap or a little pick could work. You can youtube a video of it. Another options is to go to a junkyard and cut the pigtail off. Probably cost a $1.

 

This thread which I wrote has everything you need:

Junkyard sounds like a good option, and one I would have taken had it not been fairly inexpensive on eBay. I’ll continue my troubleshooting next week after arrival.

 

I believe I found the link within your posting (Corsa?). It does appear that you have to secure some dimensions on your current connector in order to specify a replacement.

I had already ordered elsewhere, but if I do it again I may give these folks a try.

 

Thanks again. Obviously I erred in accepting what I was told at several aftermarket parts counters. EBay motors really does have everything.

I picked an example having a decent price with quick delivery, and ordered. I’ll resume troubleshooting this charging system later next week. Looking forward to the day I can stop charging my battery overnight just to run a few errands the next day!

 

I am not sure what you are trying to say but the connector should be standard. You can verify it by reading the code on the back of the connector, or by looking it up on the Toyota electronics wiring manual which is floating around here. You should not need to get too crazy with finding a replacement.

 

Your Welcome.

You might have corrosion under the insulation if the wire from the B terminal of the Alternator to the fuse block has never been changed. In fact if the battery terminals and cables havenever been changed that is a good idea.

Good luck in figuring this out.

Wonderful recommendation but, OP, I would avoid pigtails. Build the harness from scratch. I realize this is more labor and resource intensive but pigtails introduce a point of failure and electrical resistance. If you want your truck to last for many more years then soldered and-or open barrel crimped connections are those possible failure points principally due to vibration and heat. Of course, heat shielding and thoughtful design lessen that chance; but are you confident in your skills? You do you, OP, but I personally rebuilt mine from scratch and urge you do the same.
